# Using Presentment Currencies When operating in a different default currency from the channel(s) you are selling your products through, realtime currency exchange rates will be used by default. If however you define explicit per-currency prices in your Shopify store these can be synced and used through our Contextual Pricing feature. Please notify the channel(s) you are connected to if you wish to have this feature enabled for your store. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
